Vehicle control device
First Claim
1. A vehicle control device controlling a hybrid vehicle including an engine, a motor generator, a power storage device which receives an electric power from or transmits the electric power to the motor generator and can be charged and discharged, and a heating device which includes an exhaust heater using an exhaust heat of the engine and a heat pump system using the electric power of the power storage device, the vehicle control device comprising:
- a memory for storing executable instructions; and
a processing system including a processor, the processing system upon execution of the instructions by the processing system being configured to;
acquire a temperature of a coolant of the engine;
acquire a power residual of the power storage device;
determine a start timing of the heating device based on the temperature of the coolant and the power residual; and
determine a heating output corresponding to an output of an electric heater and an output of the exhaust heater in a warming-up operation, based on the temperature of the coolant and the power residual, the heating output being determined such that a timing that the temperature of the coolant reaches a temperature target value matches a timing that the power residual reaches a power residual target value.

Abstract
A vehicle includes an engine, a first MG, a second MG, a main battery which can be charged and discharged, and a heating device. The heating device includes an exhaust heater which uses an exhaust heat of the engine, and a heat pump system which uses an electric power of the main battery. A hybrid control device determines a start timing of the heating device, based on a coolant temperature and a SOC. Specifically, the start timing of the heating device is determined such that a timing that the coolant temperature reaches a target temperature matches a timing that the SOC reaches a target value. After a warming-up operation is completed, an EV travelling of the vehicle can be executed according to the electric power of the main battery charged in the warming-up operation, and a fuel consumption of the engine is improved.
